these are Crocs lightweight rain boots. excellent condition. It says size 10w but I'd definitely say they fit more like a 8.5. I bought them for myself off Marketplace and was sad they didn't fit my size 10 foot. my daughter is a size 8 and they are a little bit big on her. so im going with 8.5 for size. so basically just want to recoup some of the money I spent on them.
